Be it known that I, HENRY C. HERB, a

citizen of, the United States of America, re-

siding at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvementsin Machines for Forming Paper or Fiber Packages, of which the following is a typeemployed for the formation of a cylindrical drum or package by thewinding of a pluralityof plies ofpaper or fiber stock.

. It is the object of thepre sen't invention to obtain a construction adapted for the formation of a package in which the paper or vation of the machine.

fiber stock is reinforced by a metallic insert. To this end the inventlon consists in var1- ous features of construction as hereinafter set forth.

MACHINE FOR FORMING PAPER OR FIBER PACKAGES.

Patented June 13, 1916.

- Application filed October 21, 1913. Serial No. 796,446.

The essential operations performed by the machine are, first, the engagement ofv the paper strip with the winding drum and the winding of one or more plies thereon?- second, the delivery of the metallic reinerated to sever the paper strip when the required length has been fed, and further a suitable timed drive-mechanism by which the various instrumentalities are operated in proper sequence.

Dm'oe mechanism.For driving the machine, motion is communicated from any suitable source to a pulley G which drives a pinion G intermeshing with thejgear-wheel G? coupled by a clutch G with a shaft G, having a pinion Gr intermeshing with a gear-wheel G upon the main shaft G of the machine. Upon the opposite sides of the gear-wheel G are segmental or interrupted gear-wheels G and G, which are adapted to respectively mesh with pinions H and upon parallel shafts H. and I.

-H is agear-Wheel on the shaft H intermeshing with a pinion H which is on a shaft 1) of thelower feed-roll D. The upper feed-1'oll is driven from the. shaft! D through the medium of intermeshing gears .J J, so that the two rolls will be driven at the same peripheral speed, while their operation will be timed by the interrupted gear segment G The shaft 1 has mounted thereon, a gear-Wheel K, which'inter-,j meshes with a pinion K on the drum-shaft y F and drives the drum. Adjacent to the pinion K and coupled therewith is a gearwheel K forming the drive member of a gear-train L for driving the feed rolls L and L for the metallic reinforcement. M is a shaft adjacent to the lower feed roll L for controlling the operation of said feed rolls, and which is itself driven by a. sprocket-and-chain connection M from the 1 main shaft G Suitable locking mechanism is provided for each of the shafts H and I when not in bperation-such as starwheels H and I on the; main shaft G enbridge (3 having a roll C respecdrum shaft, said track being cut away at one point to permit the dropping of the roll C and opening of the grippers when the drum is in its initial position,

C for filling said opening when the grippers retain their engagement for more than one revolution of the drum. The detail construction of this mechanism isfully described in the prior' patent above referred to, audit is therefore only necessary to state that after once engaging with the paper the grippers retain=their engagement during the subsequent rotation of the drum' untIl the v requisite number of plies have been wound thereon. As shown and described in the prior patent; above referred to, the drum segments are collapsed and] expanded by a toggle-lever C operated by longitudinally- ,inovable bars C connected by links 0 to a sliding sleeve C actuated by a'lever, C The feedingof the paper strip is effected by the rolls D which, as already'stat-ed, are

driven from the gear-segment G when in mesh with the pinion H. This segment is so positioned and timed that the paper will start feeding at the same time that the gearsegment G, engaging with the .pinion I,

starts the rotation of the d'rum., The paper is positively fed'by the rolls speed as the drum until the grippe D at the same are operated to engage .the forward edge of the paper strip. The segment Gr then disen gages from the pinion H and permits the further feeding of the paper to be effected by the winding of-the drum, while the fric-,

tional resistance will be just sufiicient to maintain the proper tension. To cement the plies of paper to each other a paste-roll N. is arranged beneath the table E and is adapted to be pressed upward against the underside of the paper-strip. This roll is, however,

, lowered outpf contact with the strip during its initial. movement and until a length has been fed equal to one convolution upon the the pasting of the drum, thereby avoiding h I e'roll N is then paper to the drum.

i raised and, continues to apply-the adhesive to the underside of the strip until the full length has been applied, the mechanism for accomplishing this being preferably con structed as follows: 0 isa tank forthe adhesive, in which the roll N is partially immersed; O are rock arms, at the free end of which the roll N is journaledrand O are cams engaging the arms 0 to raise and lower the. same. 'The cams O are mounted and also having a constant movement.

- rects it so as to tangentially engage the wind- :M again lowers the roll L the guides or any and therefore the upon a rock shaft ()fi actuated by' a rock arm 0 from a cam 0" upon the main shaft G Means is also provided for rotating the roll N whenever it is lowered out of contact with the paper strip, this consisting 7 of gear or friction wheels N and N which engage when the roll N is lowered but which are disengaged by the raising'of the roll. Thus where anadhesive is ClIlPlOyGd which will quickly harden when exposed to the air-such as silicate of soda-incrustation of the surface of the roll is prevented by this Reinforcement applying me(ill/meant.'- The metallic reinforcen-ient, which is woundeo between the plies of'the paper or fiber stock is preferably a flat sheet of open-mesh expanded metal. This is placed upon the table B and is .fed by the operator against a stop P, which permits a portion of the sheet to extend between the upper and lower feed rolls L. and L The cam M upon the shaft M engages'aroller P upon a rock-frame P which carries the lowerfee'd' roll L and is adapted to raise and lower said frame and roll. The timing is such that during 'the initial movement of the paper stock, the roll' Lis lowered and consequently is out of contact with the metallic reinforcement, while the contact of the upper roll L is insufficient to feed the sheet. At thl proper time, the cam M will raise the frame I and the roll L pressing the hitter against the underside of the sheet and causing it to travel forward, the stop Pwhich is mhunted upon-the rock frame P being raised out of the path of-the sheet. The sheet thus, fed will pass around a segmental guide (,1 which imparts a curvature thereto and finallyidi ing-drum near the point of tangency o'fthe paper strip. 'The'feeding continues until the reinforcement'is firmly gripped between the plies of the paper, after which the cam and permits the further feeding to beeffected by the drum.

It is desirable to coat with the adhesive the side of the metallic reinforcement which comes in contact with the uncoated side of the paper. is accomplished by feeding the reinforceiniiiitupward through a well in the tank 0 and into contact with a roll R,v

which is partially immersed in the tank.

The reason for this arran'gementis that it is desirable to avoid applying the adhesive to other part of the machine, roll R is located'adjacent to the point of engagement between the reinforcement and the plies of paper on the drum, While the passing of the reinforcement through the well in the tank permits of using the one tank for both the rolls R and N v To press the reinforcement in firm contact with the paper ply on the drum a spring-pressed guide or shoe S is arranged adjacent torthedriini', but spacedtherefrom ions ofjpaper bein wound without contacthg with said gui The-added thickness ffthe reinforcement'iand the second ply of e st'ock willbrin'g the latter in contact with the guide, which will operate as a 'ser and. will hold 1 the plies from springoutward. I I

Gut- 01f 'meohanism.Before the r compleof the windingv the paper strip must be severed, which yoperation is performed by a knife bar T located above a slot in the table andin coiiferative relation with a stationary shearrfllade. TheYknifej-bar is actud b internaLcamsS' and S upon the main s aft G which engage rolls S upon the hiifebar carryingframe S and at the ever the strip. During this severing operation; the rotation" of the drum is arrested by air interruption G in the gear-segment G, thereby avoiding. straining, or danger of 6' mg the paperstrip; butas soon asthe p issevered that drum is again rotated to mplete' the winding. In starting the op rat onit is necessary to, trim the end of hefstrip square, and for. this purpose the knits-bar maybe manually operated through a p'edal U connected by the hnk U with the frame S. Q i

peratz'one -A'fter the engagement of the rastrip with the feed rolls D and the mining of the end ortion thereof by the anual operation of he pedal U, the metal: ic 'reinforcing sheets areqplaced upon the a tableBand the'machine is ready 'fortio era- 0n. tol 'lceinent sheet'between the, rolls L andL",

ns'qthe forward edge of the sheet. The u'm Qmay be ina osition where its segmetsare collapsed f dr the removal of the reviously formed package, in which posithevroll C :isgin engagement with the C in the circular track C". In the n t aljmovement of the drum, however, the 7 gttravelsup the cam side vofthe notch engages-the circular traclrC", whereby i thetroll not onlyvfastens the clips C but lso expands the drum' whenrollapsed by Q, ing. outward the segment C thereof. W 's, the segments of the drum when colapsedl are in close proximity to the circular @track, so thatthe roll traveling upon. the ck engages the segments, thereby forcing emoutward. This movementis assisted by v 1 afspringG drawing upon the toggle levers t( ;..straighten the same. This operation llipositively expand the drum so as to avoid any danger of winding the paperibout the drum in collapsed j .osition. To artthe operation thecluteh his, engaged sufiihiently to permit one or more convolurope: point inthe oycle lugs S ohsaid ams depress said rolls to cause the knile'to The operator first'adjusts the rein-- hichflinthe position-of rest of the machine a 'f'separated, and the stop P properly posi- (hole 0.

by the manual operation of a pull-rod or other control device V. This is so arranged that the clutch when thrown into engagement will continue to drive the mechanism until one complete revolution is performed, upon which the clutch is again disengiiged automatically by suitable mechanism, not shown.- The movement of the shaft G* driven by the clutch will be transmitted through the pinion G and gear-wheel G to the main shaft G, from which in turn it is intermittently transmitted to the shafts H" and I by the interrupted gear'segments G and'G as previously described. During.

. on aging the pinion I upon tl le shaft 1'',

wi l communicate motion through the gearwheels K and K to the drum-shaft, causing the'rotation of the drum at the same peripheral speed as the speed of the paper strip. The rotation of the drum will cause movement of the roll C out of the notch C in the stationary cam C, which, as above described, will positively expand the drum and effect the engagement of the grippers with the edge of the paper strip. The drum then continues to rotate until the feed rolls D cease to be positively driven by the disengagement of the gear-segment G from the pinion H, after which the paper is fed solely by the winding drum.

During the movement thus far described, the paste-applying roll N is in its lowermost position within the tank 0, and is out of contact with the paper strip, but the cam O which, through the medium of the rock arm shaft 0 and cam 0 operates the rock arms 0' to raise the roll N, is so timed that as soon as a length of paper sufiicient to form one complete convolution has passed the point opposite the paste-roll, the latter is raised and applies the adhesive to the on.-

derside of the paper strip. Th3 metallic v reinforcement, which has been stationary on the tableB during the initial operation, 1s actuated by the pressing of the lower feed roll L against the upper feed roll L, which is efiected by the cam M engaging the roll I on the rock-frame P this also disengaging the stop I. The sheet will thus be fed up around the curved guideway Q and through the slot or well in the paste recep- It will then be directed rearward by the curvature of the guide and into contact with the roll it, which, being immersed in the liquid adhcsive,will coat the lower surthe convolution orconvolutions of paperpre viousl y wound upon the drum and the portion of the strip still be'ing lwound thereon, and thus will be embedded l'retween the plies with liq' uid'adhesive on both sides thereof to cement it tothe paper, The increased thickness (if. tlie'windmgs will bring the same intofcon "tact with the resiliently-pressed shoe S 1 whichacts 'a'sa pre-sser-bar for maintaining 1 3 "'the' icon 'v olutions in firm'cont 'ct At the point' in the operation'where the full length of mpei-"strip is' passed forward of the plane of the knife-bar, movement of the drum is temporarily arrested by theinterrup't on- G in the gear-segment G, and
